As shown in accompanying drawing 3, wherein handle is fixed on the circumcision bracelet, is convenient to the rotation of circumcision bracelet. The support of the knife rest is fixed on the circumcision bracelet with bolts, and the support of the knife rest bears the circumcision spiral micrometer, and the inherent knife rest under the knife circumcision spiral micrometer. The circumcision bracelet is inserted into the inner ring of the bearing. When the handle is turned, the knife holder rotates with the bearing to drive the circumcision bracelet, and at the same time, it achieves the purpose of circularly cutting the cable sheath. The outer ring of the bearing is fixed on the flat plate in the support structure of the support plate and the support plate on the ground, and they are fixed with bolts.

As shown in FIG. 4 , the slitting and cutting mechanism is mainly composed of a flat plate 210 , a slide rail slider structure 220 , a gasket 230 on the slider, a tool device 240 , a handle 250 , and a tool holder body 260 . As shown in Figure 4. The slitting spiral micrometer is connected to the main plate of the tool holder, the front end of the main plate of the tool holder is connected with the tool device for longitudinal cutting, and the lower part of the main board of the tool holder is connected with the slider of the slide rail slider structure. When the slider moves back and forth on the slide rail, it drives the cutter device to cut longitudinally. The slide rail is fixed on the flat plate, and the cutter device is facing the middle of the whole device, which ensures that the cutting position is at the central axis of the cable during longitudinal cutting.

As shown in FIGS. 5 and 6 , the support plate support mechanism 100 is mainly composed of five parts: a flat plate 210 , a horizontal frame 110 , a support plate 120 , a support leg 130 , a ground support plate 140 and an underframe 150 . As shown in accompanying drawing 5, described base frame bottom is fixed with connection block, and described connection block is provided with round head keyway, and base frame fastening bolt 160 passes through round head keyway to fix base frame and ground support plate, and described The bottom of the supporting legs is in the shape of a circular table, distributed at the four corners of the ground support plate, and one side of the chassis is provided with cable fastening bolts 170 for fastening the cables; The arc of the underframe is concentric, so a bolt hole has been opened at the center of the arc of the underframe. In this way, the cables are fastened through the bolt holes on both sides of the two bottom frames with bolts. This has the advantage of centering the cable even when the cable is not straight or partially bent. In addition, a round head keyway is provided on the bottom frame, as long as there is a bolt hole on the ground support plate, the left and right movement of the bottom frame can be controlled. When the size of the cables is different, it can be used to adjust the direction of the left and right movement of the chassis, so as to control the clamping of the cables. The support structure adopts a symmetrical way to center the cable, and there are rail grooves and small holes on the ground support plate for positioning and limiting of the chassis. The support legs play the role of supporting the ground support plate, mainly for connection and support, and can make the whole structure level and the same height under the action of the support legs.

The support structure adopts a symmetrical way to center the cable, and there are rail grooves and small holes on the ground support plate for positioning and limiting of the chassis. The support plate is used to support the ground support plate and the flat plate, and is used for connection and support. The horizontal frame is mainly to connect and fix the three base frames together, which is convenient for the connection of the device and the positioning of different cable lengths. The right side of the ground support plate is used to clamp the bottom frame with bolts for lateral positioning, and the cable does not slip when the cutter structure performs longitudinal cutting. The flat plate is connected with the slide rail in the longitudinal cutting structure, and the flat plate and the ground support plate are connected with the bearing cartridge by the sticky plate.

The original intention of this design is to cut the cable sheath conveniently and clamp it in the fastest time, so the ring cutting adopts the bearing structure, and the bottom frame is used for clamping when cutting longitudinally, and the sliding block slide rail structure is used for pushing. Can save time and effort and convenient and effective mining. The cutter support is fixed in the handle device when cutting in the circumferential direction, so that the circumcision can be ensured when the knife rotates along the circumcision bracelet. When cutting longitudinally, the tool holder is fixed on the main body plate of the tool holder to ensure that the knife moves on the slide rail along the slide block.

For some cables that are not completely straight, a number of different positions are used to set the chassis at intervals, and the cables are cut as straight as possible, avoiding the situation that the cables are not straight under certain circumstances and the cutting depth is inconsistent occur.

As shown in Fig. 7 and Fig. 8, tool device mainly is by: described knife rest 260 is mainly made up of the second screw micrometer 261, the cover 262 on the second knife rest, the handle 263 on the second knife rest, the second cutter cover 264, the second blade 267, the second cutter part 265, the cutter part fixing bolt 266, the fixing bolt 267 on the second knife rest, the cover fixing bolt 267 on the second knife rest, and the cover and the second knife rest There is a rectangular slot between the upper handles of the two tool holders, and a rectangular block is installed in the rectangular slot. The lower end of the second spiral micrometer withstands the rectangular block, and the lower end of the rectangular block withstands the second tool part. Tighten the fixing bolt of the tool part. , to make it tighten the rectangular block. What this step completes is the fixing of the tool rest as a whole. After the spiral micrometer has adjusted the slitting depth, tighten the cover fixing bolts on the second knife rest, so that the cover fixing bolts on the second knife rest are pressed against the rectangular block to fix the entry of the second blade. Knife amount. The bolt 268 for fastening the screw micrometer is fixed on the cover of the second knife rest. When the blade in the tool part is on the cable, the bolt 268 for fastening the screw micrometer is loosened, and the screw micrometer is rotated. The downward movement of the screw micrometer drives the downward movement of the tool part. When the falling distance of the tool part reaches the specified requirement, the screw micrometer stops moving, and the bolts of the screw micrometer are tightened. The advantage of this design is that the feed rate of the cutter part is controlled by the screw micrometer, and it can also prevent the entire cutter body part from moving downward due to gravity to accurately locate and reduce errors.

Combining circumcision and slitting into one, it can save time and effectively perform circumcision and slitting at the same time.

Using the bearing to rotate for circular cutting and using the slide rail for longitudinal cutting can save labor and cut efficiently.

A certain arc is programmed on the bottom frame, which can reasonably locate the cables; it is very convenient to fix, disassemble and locate the bottom frame by clamping the bottom frame with bolts.

In this device, firstly, the cable 400 is fixed with the base frame and the bearing, then the circumferential cutting is performed, and finally the base frame is loosened to further push the cable into the supporting structure of the support plate, and then longitudinal cutting is performed.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these improvements and Retouching should also be regarded as the scope of protection of the present utility model.
